Never use heat on a building to remove paint.
Another home destroyed, some odd millions down the tubes and 4 firefighters hurt today because a worker was using a propane torch to remove paint. Heat guns and torches should be illegal to use on the actual building. Take the wood off and use it, that's another story, but never use that method on the building. It's just too freaking dangerous. And can anyone say lead poisoning? That's exactly what happened to my wacky friends kids, from illegal torch burning of her house to prep it for painting.
